A correopening 35, extends across the window opening sponding lower glazed panel 23, in plane with under the frame head 31 and terminates downthe swing panel 2 extends across the lowerpart wardly at approximately above the sill 32 at about of the window opening, from the sill upwards to thesame level as thetop of the fixed sill panel 53 the same height as the panel 25 and close to it; 30. A ventilation well 40 is thus formed. below 51% said main panel 38 between the sill panel 30 and a glazed panel lliwhich extends up from the inner sill of the window frame 32 parallel with and at approximately the: same height as the panel 30. In this case the main panel 38 is in one piece.

By extending the top edge of the inner sill panel 45 above the level of the top of the fixed outer panel 30 and hinging said panel 15 to swing both inwards and outwards, the necessary clearance can be provided for enabling the main panels 33 and 38 to swing inwards, while when the main panels are in their normal position the window opening may be entirely closed by swinging the panel 45 in an outward direction until its top edge bears against the lower framing of the main panel 38.

When constructing windows of great width itis convenient for the main panels to be divided vertically into two or more portions. This is seen in Figure 4 which is a sectional plan view across a window similar to that'shown in Figure 2. In the modification the panels l3 and I8 are framed up in two equal portions so that the adjacent vertical parts of the framing abut one another as in casement sashes while the outer vertical parts are hinged to the opposite reveals, whereby both double sashes I3 and I8 are adapted to swing inwardly.

From the foregoing description it will be seen that the arrangement of panels provides for minimizing sound transmission while permitting transmission of light from one side to the other side of the window.

It will further be understood that some or all of the unglazed surfaces within the aperture may be lined or treated with any known material specially adapted for sound wave dampening.

I claim:

1. The combination with a window frame, of a window fitment in the framecomprising inner and outer vertically disposed glazed structures which are separated laterally by an air space and overlap to a considerable extent, the outer frame structure engaging the frame at its two sides and at the'sill but being spaced fromv the top of the frame, said outer structure being divided horizontally into upper and lower panels, the upper one of said panels being hingedly mounted whereby it may swing inwardly, the inner glazed structure engaging the window frame at its two sides and top of the latter, and having its lower end spaced from the sill, the inner structure comprising a hingedly mounted portion adapted to swing inwardly to permit the upper panel of the outer structure to swing inwardly.

2'. The combination with a window frame, of a window fitment in the frame comprising inner and outer vertically disposed glazed structures which are separated laterally by an air space and overlap to a considerable extent, the outer frame structure engaging the frame at its two sides. and at the sill but being spaced from the top of the frame, said outer structure being divided horizontally into upper and lower panels, the upper one of said panels being hingedly mounted whereby it may swing inwardly, the inner glazed structure engaging the window frame at its two sides and top of the latter, and having its lower end spaced from the sill, the innerstructure comprising upper and lower panels hingedly mounted in the frame, the lower one of the last mentioned panelsbeing adapted to swing inwardly to permit the upper panel of the outer structure to swing inwardly.

3. The combination with a window frame, of a Window fitment inthe frame comprising inner and outer vertically disposed glazed structures which are separated laterally by an air space and overlap to a considerable extent, the outer frame structure engaging the frame at its two sides and at the sill but being spaced from the top of the framasaid outer framev structure being divided horizontally into upper and lower panels, the upper one of said panels being hingedly mounted whereby it may swing inwardly, the inner glazed structure engaging the window frame at its two sides and top of the latter, and having its lower end spaced from the sill, the

inner structure comprising a panel of substantially the same height as the inner structure, hingedly mounted in the frame and adapted to swing inwardly to permit the upper panel of the outer structure to swing inwardly 4. A window fitment consisting of two main vertically disposed framed glazed structures which are separated laterally by an air space, comprising an outer framed structure fitting the window aperture at the two sides and the sill. leaving an opening at the top side, said structure being divided horizontally into two panels, an innor framed structure fitting the window at the two sides and the top leaving an opening at the lower side, this framed structure being divided horizontally into two panels and having hinges on the lower panel, and a further framed structure separated laterally by an air space from the inner framed structure, this further structure being divided horizontally into four separate narrow panels of substantially equal height, one

such panel being fixed to the sill and another at the top of the aperture and each closing the window aperture at the two'sides, the other two panels having sliding means enabling them to slide respectively upwards and downwards close to the first two mentioned narrow panels,

so that whenthe said inner sliding panels are opened they form a clear space through which the hinged panels of the main structures can pass.

5. The combination with a window frame, of

a window fitment in the frame comprising inner and outer vertically disposed glazed structures which are separated laterally by an air space and overlap to a considerable extent, the outer frame structure engaging the frame at its two sides and at the sill but being spaced from the top of the frame, said outer structure being divided horizontally into upper and lower panels, the upper one of said panels being hingedly mounted whereby it may swing inwardly, the in-' ner glazed structure engaging the window frame at its two sides and top of the latter, and having its lower end spaced from the sill, the inner structure having its lower edge arranged in substantially the same plane as the upper edge of the lower panel of said outer structure, the inner structure having a portion hingedly mounted in the window frame and adapted to swing horizontally inwardly to permit the upper panel of the outer structure to swing inwardly, and an additional panel separated laterally from the which said additional bane} is movably mounted in the frame whereby it may be opened or closed to adjust the degree of ventilation.

n i 7. A combination as claimed in claim 1 in which the upper panel of the outer structure and the hinged portion of the inner structure are hinged to swing horizontally inwardly.

8. A combination as claimed in claim 1 in which the hinged panel of the outer structure and the hingedly mounted portion of the inner structure are each divided vertically into two sections, each section forming a vertically hinged 5 sash adaptedto swing in a horizontal plane.
